Holy #$%^ that is what I call a lot of damage.

A key mechanic to the fight is the Gaseous Blight that covers the floor of the room. Its basic function is to do damage-over-time to the entire raid - nothing too significant, but it all adds up. Festergut will periodically Inhale Blight, taking up about a fourth of the Blight in the room. This will reduce the damage it does, will improve the visibility of the floor (perhaps so you can see the Vile Gas and get away from it?), and increase the boss' damage and attack speed (and size) by 30%. Every fourth inhale, Festergut will cast Pungent Blight instead (there will be very little Blight left). Pungent Blight will do a tremendous amount of Shadow damage to everybody in the raid, and will return the Blight to its maximum concentration. The boss' damage buff will also be reset, and the cycle will repeat.

I took that out of the guide to kill him when more people look at comments than the raid guides.
